[0024] The following is a clear and complete description of the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0025] Example

[0026] The present invention will be further described below with reference to the accompanying drawings.

[0027] like Figures 1 to 6 As shown, the embodiment provides a pushing device in a garbage truck compartment, comprising a hydraulic cylinder assembly 2 mounted opposite to the inner wall of the compartment 1, and further comprising:

[0028] The pushing plate 3 is vertically located in the carriage 1 and is connected to the hydraulic cylinder assembly 2. A shaking chamber 31 is provided in the pushing plate 3. The shaking chamber is provided with several groups of shaking block assemblies arranged along the width direction of the pushing plate 3 and eccentric blocks 32 that drive each group of shaking block assemblies to work. The shaking block assembly includes several fan-shaped shaking blocks 33 arranged along the height direction of the pushing plate 3. One end of the fan-shaped shaking block 33 is exposed from the pushing plate 3 and is arranged near the garbage end. A limiting slot 34 is provided on the fan-shaped shaking block 33, and a guide rod 35 is passed through each limiting slot 34. A limiting block 36 adapted to the limiting slot 34 is installed on the guide rod 35. The top of the guide rod 35 is provided with a lifting plate 37 connected to the eccentric block 32.

[0029] The working principle and beneficial effects of the above technical solution are:

[0030] The utility model discloses a pushing device in a garbage compartment. When the hydraulic cylinder assembly 2 works, the hydraulic cylinder assembly 2 can extend a first distance and a second distance. The second distance is extended on the basis of the first distance, and the second distance is smaller than the first distance. When the hydraulic cylinder assembly 2 extends the first distance, it drives the pushing plate 3 connected to the hydraulic cylinder assembly 2 to move in the extension direction of the hydraulic cylinder assembly 2 in the compartment 1. The pushing plate 3 is close to the garbage end and completes pushing the garbage in the compartment 1. When the garbage pushing is completed, the garbage in the compartment 1 is manually taken out, and the hydraulic cylinder assembly 2 extends the second distance. At this time, the eccentric block 32 located in the shaking chamber 31 rotates. The eccentric block 32 periodically presses the lifting plate 37, thereby driving the guide rod 35 connected to the lifting plate 37 to perform a periodic sinking movement. Under the cooperation of the limit block 36 and the limit slot 34 on the guide rod 35, the fan-shaped shaking block 33 is driven to rotate. The fan-shaped shaking block 33 pushes the pushing plate 3 close to the garbage end, thereby pushing out the garbage attached to the pushing plate 3 close to the garbage end. The utility model provides a pushing device in a garbage truck compartment, wherein the fan-shaped shaking block 33 pushes out the pushing plate 3 near the garbage end, thereby pushing out the garbage attached to the pushing plate 3 near the garbage end, thereby eliminating the need for manual removal.

[0031] In one embodiment, it further includes:

[0032] The guide wheel assembly 4 includes a guide rail 41 installed oppositely on the inner wall of the carriage 1, a bow-shaped fixing frame 42 installed on the push plate 3, and four guide wheels 43 are installed in groups of two at both ends of the bow-shaped fixing frame 42. The guide wheels 43 run in the guide rail 41, the transmission shaft 44 is installed in the shaking chamber 31, and the eccentric block 32 is installed on the transmission shaft 44. The two ends of the transmission shaft 44 are penetrated by the bow-shaped fixing frame 42 and extend into the guide rail 41. Rotating gears 45 are installed at both ends of the transmission shaft 44, and a rack 46 adapted to the rotating gear 45 is installed in the guide rail 41. The guide wheel 43 is set away from the rack 46.

[0033] The working principle and beneficial effects of the above technical solution are:

[0034] The hydraulic cylinder assembly 2 works, thereby driving the push plate 3 connected thereto and the bow-shaped fixing frame 42 installed on the push plate 3 to move horizontally, and then driving the guide wheel 43 installed on the bow-shaped fixing frame 42 to slide in the guide track 41, thereby limiting the push plate 3. When the hydraulic cylinder assembly 2 extends the second distance, the rotating gear 45 engages with the rack 46, thereby driving the transmission shaft 44 connected to the rotating gear 45 to rotate, and the transmission shaft 44 drives the eccentric block 32 installed thereon to rotate. The eccentric block 32 periodically presses the lifting plate 37, thereby realizing the rotation of the fan-shaped shaking block 33, and the fan-shaped shaking block 33 pushes the push plate 3 close to the garbage end.

[0035] In one embodiment, the cross section of the guide track 41 is C-shaped, the guide wheel 43 runs on the bottom of the guide track 41 , and the rack 46 is installed on the top of the guide track 41 .

[0036] The working principle and beneficial effects of the above technical solution are:

[0037] When the hydraulic cylinder assembly 2 is working and the hydraulic cylinder assembly 2 is extended by a first distance, the guide wheel 43 moves in the guide track 41 and the rack 46 is not engaged with the rotating gear 45. When the hydraulic cylinder assembly 2 is extended by a second distance, the guide wheel 43 continues to move in the guide track 41 and the rack 46 is engaged with the rotating gear 45.

[0038] In one embodiment, the bottom end of the guide rod 35 is mounted in the shaking chamber 31 via a lower sliding frame 47 .

[0039] The beneficial effects of the above technical solution are:

[0040] The arrangement of the lower sliding frame 47 serves to limit the bottom end of the guide rod 35 .

[0041] In one embodiment, the guide rod 35 is installed in the shaking chamber 31 through an upper sliding frame 48 near the end of the lifting plate 37. A spring mounting frame 49 is installed near the end of the guide rod 35 near the lifting plate 37. The upper sliding frame 48 is located between the lifting plate 37 and the spring mounting frame 49. The return spring 40 is sleeved on the guide rod 35 and connected between the upper sliding frame 48 and the spring mounting frame 49.

[0042] The beneficial effects of the above technical solution are:

[0043] The eccentric block 32 periodically presses the lifting plate 37 , and the guide rod 35 slides on the upper sliding frame 48 near the end of the lifting plate 37 , and the return spring 40 periodically extends.

[0044] In one embodiment, the push plate 3 is provided with an installation opening connected to the shaking chamber 31 near the garbage end, and the fan-shaped shaking block 33 is installed on the inner wall of the installation opening through the flip shaft. The fan-shaped shaking block 33 covers the installation opening, and a reset torsion spring 38 is sleeved on the flip shaft.

[0045] The beneficial effects of the above technical solution are:

[0046] The eccentric block 32 periodically presses the lifting plate 37, and the fan-shaped shaking block 33 flips outward on the mounting port with the flip axis as the center. The reset torsion spring 38 is twisted under the force, and when the lifting plate 37 is lifted, the reset torsion spring 38 drives the fan-shaped shaking block 33 to reset on the mounting port.

[0047] In one embodiment, the number of sector dither blocks 33 in each dither block assembly is at least 6.

[0048] In one embodiment, the push plate 3 is connected to the hydraulic cylinder assembly 2 via reinforcing ribs.

[0049] The specific structure of the hydraulic cylinder assembly 2 has been disclosed in Chinese patent CN220222177 U and will not be repeated here.

[0050] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
